Anchor DMUs are a new class in the general classification of Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). An anchor DMU in DEA is an extreme-efficient DMU that defines the transition from the efficient frontier to the free-disposability part of the boundary of the Production Possibility Set (PPS). In this paper, the anchor points of the PPS of the CCR model are investigated....

In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...

At present, researches on floating offshore wind turbine are mainly focused deep water areas beyond 50 m, and less research has been conducted for shallow water. Considering that the fan still many application values in 30 m–50 m area, it is necessary to study area. With design depth effect of topography, environmental condition complex. Therefore, relatively difficult mooring system. In this p...

Based on a previously designed variable-stiffness load transfer component (LTC), novel dispersed-tendon cable anchor system (CAS) was developed to increase the anchoring efficiency of large-diameter basalt-fiber-reinforced polymer (BFRP) cables. The static behaviors CAS are then numerically evaluated by simplified three-dimensional finite-element (FE) model and implemented in full-scale BFRP ca...

Abstract This article introduces a cable-driven lower limb rehabilitation robot with movable distal anchor points (M-CDLR). The traditional parallel robots (CDPRs) control the moving platform by changing length of cables, M-CDLR can also adjust position point when moves. this proposed has gait and single-leg training modes, which correspond to plane space motion platform, respectively. After in...

a large number of authors have studied to find out how to control scouring around a pier along direct stream. the objective of this research is then to study a scour pattern around such piers on curves rivers due to the fact that there may be a difference between a flow pattern on a direct line and the meander. thus, this study tries to check whether the use of cable and collar alone and in a c...

Recently, the rapid advancement of IT industry has resulted in significant changes audio-system configurations; particularly, audio over internet protocol (AoIP) network-based audio-transmission technology received favourable evaluations this field. Applying AoIP a certain section multiple-cable zone is advantageous because installation cost lower than that for existing systems, and original so...

The stability of the gas extraction roadway is very important for safe mining coal and gas. compression arch formed by combined action prestressed bolt (cable) support surrounding rock has been widely used in engineering practice roadway. It great application value to analyze influence parameters on arch. In this paper, with deep Huainan Huaibei area Anhui Province, mechanical are measured via ...
